付き２サイクルエンジン。[Claims for Utility Model Registration] (1) A vehicle having an intake valve and an exhaust valve, a mechanical supercharger provided in the intake passage, a bypass passage bypassing the mechanical supercharger, and a computer installed in the bypass passage. In a two-stroke engine that controls the amount of supercharging by providing a bypass valve whose opening and closing are suppressed by A two-stroke engine with a mechanical supercharger that controls the bypass valve to close. (2) An intercooler and an intercooler bypass passage having a switching valve are provided between the intake valve of the intake passage and the mechanical supercharger, and the intake air is directed to the intercooler bypass passage side during startup and when the computer is cold. A two-stroke engine with a mechanical supercharger as set forth in claim (1) of the utility model registration, wherein switching of a switching valve is controlled so that the flow is controlled to flow at
